Hello

New to forum I don’t know if I should post here or to a specific area sorry admins. I went through all the stickies on the forum about AC. Got AC fault code b1241 added 134a 2 days later ec light back on with same code b1241. I’m assuming I have a leak in the system. But, before I go to mechanic to do leak test I would want to get the data for 1-8. As soon as I get the numbers I will post them.

1 To run the numbers 1-8. I turn off EC light off, then do the diagnostic?
2 Does it matter if the car is in the morning or evening to get the numbers?
3 Does anyone know a mechanic in San Francisco or neighboring areas that I could go to get ac leak test?

thank you
